The U436-06N-GBWUSB 3.1 Gen 1 Type-C to Gigabit Ethernet NIC Network Adapter allows USB Type-C computers, laptops and smartphones without an NIC (Network Interface Controller) to connect to a network or the Internet using an Ethernet cable. It’s a more convenient and less expensive way to connect to the network than opening your device and installing an internal Ethernet card. Connect the adapter’s USB-C connector to your device’s USB-C port, and connect the adapter’s RJ45 port to your network or Ethernet cable. Just plug and play with no drivers or external power supply needed. It’s compact and lightweight for easy carrying in your laptop bag.
